This is complete nonsense.
Interpol invovlemnt in this kind of charges is unheard of.
If you have no idea what you're talking about, everything is "unheard of".
Where a European State seeks to prosecute someone in another European country it is completely normal for Interpol to handle the communication between forces, and (according to Interpol's stats, and counting both formal notices and communications only sent to a particular country) happens about 20,000 times a year.
Notices can be issued for a wide range of offences. The first page of published notices on the Interpol website included, at the time of this comment, individuals wanted in connection with murder, rape, sexual assault, forging a passport and "unlawfully using a computer with the intention to commit an offence".
The constant monitoring of his residence by several UK policemens is also unheard of
This is a little misleading, since it ignores the obvious reasons why this is the case: it ignores that Assange's case is very unusual, since the police know exactly where he is and have a warrant for his arrest, but cannot carry it out; and it ignores that Hans Crescent and the surrounding streets are home to a number of embassies and missions, meaning that there would often be police there in any case.
It's also not true to say that it's unheard of - in other cases of people taking refuge in embassies, police or other state authorities have waited outside to apprehend them.
he was questioned, than he was released and told he can travel off the country, after he did it, suddenly, both of the "victims" changed their minds and he is wanted for another questioning again
Do you have a source for this? I've never heard that the alleged victims "changed their minds" (which, I feel compelled to say, is a bit of a distasteful turn of phrase) and it would surprise me that their statements would be released to the public.
